Answer:
Welllllll
Explanation:
It is at a relativley low cost. It also has high energy density and it is throium. We have more than 80 years worth of uranium.
Explanation:
F = k |q1| |q2| / r^2
k = 9 * 10^9
q1 = - 2.5 C
q2 = 2 C
r = 100
r^2 = (10^2)^2 = 10^4
F = (9*10^9) * ( 2.5 ) ( 2) / ( 100)^2
F = 45* 10^9 / 10^4
F = 45 * 10^9 * 10 ^ -4 = 45 * 10^5 N
F = 45 * 10 ^ 5 N
Answer:
Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), and one complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi).
Explanation:
Given that the mass is m = 0.2 kg and the displacement is x = 3 cm = 0.03 m
We have to find the spring constant and potential energy.
The spring constant can be calculated by the formula
Here, k is the spring constant.
g = 9.8 m/s^2 is the acceleration due to gravity.
Substituting the values, the spring constant will be
The potential energy can be calculated as
